In oil and gas well completion, production, or workover operations, controlling fluid communication between the annular area (the space between the casing and production tubing) and the interior of the production tubing is critical. To achieve this, the Seal Stack serves as an efficient sealing solution, widely used in wellbore tools, especially in key equipment like sliding sleeves. This article ...
(I) Application in hydraulic cylinder 1. Piston seal: The piston seal located on the piston head is usually made of rubber or plastic. Its main function is to prevent hydraulic oil from leaking from the piston head. During the operation of the hydraulic cylinder, the piston seal can maintain good sealing performance under different working pressures by virtue of its own material characteristics, e...
NORSOK standards are formulated by the Norwegian petroleum industry to ensure that the development and operation of the petroleum industry is sufficiently safe, value-added and cost-effective. NORSOK standards are intended to replace the specifications of the oil companies as far as possible and serve as a reference for the regulations of the authorities. The broad range of materials selected for ...

The following is a description of packer element: Product types: Single cartridge packer element: simple structure, consisting of a single rubber element and metal parts, suitable for some shallow Wells or simple working conditions wi...
Choosing the right seal for cryogenic valves is critical to ensure reliable performance in extremely low-temperature environments. Here's a detailed guide to help you make an informed decision: Key Factors to Consider: 1: Operating Temperature Range Cryogenic valves typically operate at temperatures as low as -196°C (-320°F) for liquid nitrogen or even lower for liquid helium. Ensure the seal mate...
Heat treatment has become a key step in the manufacturing of sealing springs, making significant contributions to improving their efficiency, durability, and service life. This treatment involves strategic applications of heat and cooling methods, intentionally altering the physical and chemical properties of the material. It is mainly applied in the metallurgical field and also greatly beneficial...
Pressure pumping, also known as hydraulic fracturing, is a well stimulation technique used to extract natural gas and oil from low-permeability formations such as tight sandstone, shale, and some geothermal reservoirs. Natural gas and oil are transported to the wellbore through a high-pressure pump (i.e. fracturing pump) composed of a power end and a fluid end, which pumps sand or ceramic proppant...
